/Engine/Source/Runtime/AudioExtensions/Public/IAudioParameterInterfaceRegistry.h
Interface for parameterizing data provided to or coming from an executable audio unit (ex. Sound like a MetaSoundSource, arbitrary DSP graph like a MetaSoundPatch, etc.). Can be used generically for processing either logically at a control or Game Thread tick rate (ex. SoundCues), or by an underlying DSP operation via the Audio Render Thread or delegated task (ex. MetaSounds, custom SoundGenerator, etc.)
